What angle does an arc 6.6cm on length subtends at the centre of a circle of radius 14cm? take ​

Given:

Arc length = 6.6 cm

Radius = 14 cm

To find:

The angle subtended by the arc at the center.

Solution:

The formula for arc length is:

Where, s is the arc length, r is the radius and is the central angle in degrees.

Putting ,we get

Therefore, the measure of the central angle is .

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

50-38=12
